PROBLEM TO BE SOLVED: To change a ready-to-win appearance ratio by changing a ready-to-win probability even in the same situation.SOLUTION: A ready-to-win probability is configured to be determined based on a type of the preceding jackpot and a state when the preceding jackpot is won. Thus, even in a situation in that a game state of ready-to-win determination is the same, the ready-to-win determination may be performed with a different ready-to-win probability based on the type of the preceding jackpot and the state when the preceding jackpot is won. As a result, the ready-to-win probability can be changed even in a situation, where the game state of the ready-to-win determination is the same, and a variation game can be executed with a ready-to-win probability suitable for the situation. |
